unrecognized option '-mcpu=r4600'

i dont think this was a help to you. -mcpu is a valid gcc option, -mCPU
is not.

>Results in Error:

the preprocessor is probably taking -m as the argument and then passing
along the remaining CPU=r4600

suggest going back to -mcpu=r4600. are you sure r4600 is a valid cpu?

try a more common cpu type first and make sure that works ok.

Subject: unrecognized option '-mcpu=r4600'


Hi, All,

I am frustrated these days by a compiling error when I try to cross
compile
linux. Here are the data I used to compile the toolchain: crosstool
0.26
gcc-3.2.3 glibc-2.3.2 linux-2.4.18

I successfully compiled the toolchain, but when I try to use it to
cross
compile linux, the following error occurs:
        .../.../as: unrecognized option '-mcpu=r4600'

I even tweaked the mips.config a little bit to support MIPS32=y, still
does
not work. I tried other options as well, no luck at all.

Here is the compile command that results in error:
/opt/crosstool/mipsel-unknown-linux-gnu/gcc-3.2.3-glibc-2.3.2/bin/mipsel-unk
nown-linux-gnu-gcc -D__KERNEL__ -I/home/build/test/linux/include 
-Wall
-Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common
-g
-fomit-frame-pointer -I /home/build/test/linux/include/asm/gcc -G 0
-mno-abicalls -fno-pic -pipe -mcpu=r4600 -mips2 -Wa,--trap
-DKBUILD_BASENAME=main -c -o init/main.o init/main.c

Any help is greatly appreciated.

Thanks

John
